Linux kernel v6.9 has changed the symlink to point to the parent device. This breaks fbdev_open() detection logic. Change it to use the subsystem symlink instead which will remain stable. Kernel v6.8: [ 14.067] (II) fbdev_open() sysfs_path=/sys/class/graphics/fb0 [ 14.067] (II) fbdev_open() buf=../../devices/platform/vesa-framebuffer.0/graphics/fb0 Kernel v6.9: [ 15.609] (II) fbdev_open() sysfs_path=/sys/class/graphics/fb0 [ 15.609] (II) fbdev_open() buf=../../devices/pci0000:00/0000:00:01.0/vesa-framebuffer.0/graphics/fb0 Originally found in automated Debian ISO QA testing [0] and confirmed in Linux [1].

X Server
The X server accepts requests from client applications to create windows, which are (normally rectangular) "virtual screens" that the client program can draw into.
Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders.
For a comprehensive overview of X Server and X Window System, consult the following article: https://en.wikipedia.org/wiki/X_server
